Wide visible-range activatable fluorescence ZnSe:Eu3+/Mn2+@ZnS quantum dots: local atomic structure order and application as a nanoprobe for bioimaging

To develop fluorescent bionanoprobe for cellular imaging, it is crucial to get precise insight on the particle–cell interaction, optical properties of QDs in and out of the cell, their movement in and out of the cell, and the final fate of particle.
